Paper Abstract

An ir spectrometer, used to obtain measurements of faint atmospheric emission spectra from a rocket carrier, is described. The sensor scans the 2.07 to 5.47 μm spectral region at the rate of 2 scan/s. The spectral resolution of the sensor, which employs a circular variable filter (CVF), ranges from 1.0 to 3.0%. The entire optical subsection, indium anti-monide detector, CVF, silicon lens, baffle, and removable cover are cooled below 80° K in a high-vacuum Dewar system. The noise equivalent spectral sterance [radiance] of the spectrometer at 5.3 μm is 1.93 x 10-10 (W cm-2sr-1μm-1).
